And there are additional costs if you're not nice on Econologie : Mrgreen:

Well then look by simulation if it confirms that the formula
F = 1/2 Cx Ro SV^2 is verified with the example of a disk (a disk for
stick with my original question).

This formula is the one that bases my calculation and it is the only point that experience
concrete could invalidate.

It would be a scoop, it would call one thing into question
universally accepted, verified, measured, and concretely applied
a thousand times, but I believe that until your simulator has confirmed
you won't be convinced.

To do what ?

To be insulted and belittled afterwards?

You will inevitably be in contradiction with the CFD results...much more precise than these equations (the Cx, which this equation considers as constant for a shape, in fact varies according to speed, pressure, viscosity, roughness... at least...)

Christophe, let’s apply your logic regarding the virtues of simulation
and then let's talk. Do you want to?

Measure, please (my Christophounet who I love and adore :? ), strength
that a disk of unit surface area, of given roughness, undergoes at a given atmospheric pressure,
for different wind speeds, and give the results.

Don't you understand what about "it's more free"?

Back to "hydraulic, wind, geothermal, marine energy, biogas ..."
